first Green LED should be on and then start flashing
after the time delay to 'on' has expired. The Air Cleaner
has to have a call for operation for the first Green LED
to flash on and off. (A call for indoor blower or heat is
a call for operation.)
Step 4
When the first Green LED is flashing on and off con-
nect the High Voltage Probe and compatible volt/ohm
meter per their manufacturers' instructions.
Step 5
Touch the tip of the High Voltage Probe to the Power
Door High Voltage terminal and read the volt meter.
Step 6
If the voltage read during this test is 9.6 KV + or – 600
volts the Power Door is working correctly. Replace
Power Door with a new Power Door if the high voltage
is not correct.
Step 7
Turn off the Air Cleaner by pushing the POWER but-
ton.
Step 8
Remove the wire and tape used to defeat the interlock

Step 9
Replace Power Door.
TESTING WITH A SCREWDRIVER, A JUMPER
WIRE AND A DRY PIECE OF PAPER
Step 1
Turn off the Air Cleaner and remove the Power Door.
Step 2
Form a piece of wire that will go through the interlock
switch opening and depress the interlock switch. Tape
it in place. See Figure 24.
Step 3
Tape a piece of paper to a screwdriver blade with ½
inch of the paper sticking out in front of the blade. Do
not put the tape over the end of the screwdriver blade.
CAUTION
May Cause Damage. Do not expose the filter to UV
light. UV light can cause the plastic materials to
deteriorate which may lead to filter damage.
Step 4
Connect the jumper wire using the alligator clips to
the screwdriver and the Power Door metal frame as
illustrated in Figure 26.
